How to setup a keyboard shortcut to custom toolbar?

I just wanted to know how i would go about setting up a key to activate a toolbar i made. The toolbar is basically a version of the drivetest toolbar in the faq section and i have given each drive a mnemonic shortcut such &C for c drive and so on. What i would like to be able to do is hit a key which gives the toolbar keyboard focus then hit my drive letter which will activate its menu and from there select a directory. Is this possible or do i have to make it a menu such as File,Edit, View etc.?

thx

It doesn't look like you can currently use the &Label-style shortcuts for buttons which are directly on the toolbar (it only works for menus and items within menus).

You can assign a hotkey to any button, though. Just edit the button and click on its Hotkey field.
